The green peach aphid, Myzus persicae (Sulzer), is an important pest of agricultural and horticultural crops. Its complex life cycle and genetics are the main factors influencing population outbreaks. The RAPD technique with 7 random primers was used to analyze DNA polymorphism in seven forms of M. persicae , which were: the mother of mating forms (alate), mating females (apterous), males (alate), eggs, the fundatrix (apterous), virginoparae (apterous) and virginoparae (alate). The results showed that eggs had the largest genetic variation, followed by the sexual forms with the parthenogenetic forms having the least amount of variation. There was a close genetic relationship between the fundatrix (apterous), virginoparae (apterous) and virginoparae (alate) in the green peach aphid.
